Matrix multiplication doesn't works if gridDim increase 80

[Aman1]

If i tried to run the attached program then it works fine till gridDim=80 (for square matrix of size equal to gridDim) but when i increase the size to 88 or more then it gives the constant value 2147483647 after some array value.

Please help me to find out the issue.

This is probably an overflow problem, 2147483647 is the largest representable positive signed 32 bit integer value.

2^31 - 1 = 2147483647
